Horniness scale
Each game gets a score from 1 to 5 hearts. Higher means more explicit adult content.
| Score | What it means |
|---|---|
| 1 | Raunchy / softcore — suggestive themes, light fanservice, or mature humor; little or no on-screen explicit sexual content. |
| 2 | Spicy but restrained — clear adult intent (nudity, strong innuendo, or brief suggestive scenes) without sustained explicit focus. |
| 3 | Clearly adult — recurring sexual content or nudity as a meaningful part of the experience, but not the sole focus of the game. |
| 4 | Strongly explicit — graphic sexual themes, extended explicit stills or text, or gameplay built heavily around adult situations. |
| 5 | Explicit and often animated — graphic sexual content that is frequently animated or interactive; core to what you see and do in the game. |
